What you can do in Foundling on the web
Symptom journal with real trends
Severity 0–10, the affected body systems from the same twelve-system list, and a private note — charted over 30, 90 or 180 days with an average that compares against the window before.
82 rare diseases, ICD-10 indexed
The bundled library the iPhone app ships — Ehlers-Danlos, POTS, MCAS, Fabry, Pompe, Wilson’s and 76 more — searchable by name, ICD-10 code, disease group or abbreviation, with Suspected / Active / Managed / Resolved status.
Medications and care team
Drug, dose, route, schedule, who prescribed it, start and stop dates, side-effect notes — plus every specialist with their practice and a tap-to-dial direct line.
A searchable document vault
Add a lab panel, imaging report or consult note with its text (typed, pasted or imported from a .txt file) and search every word of every report at once.
Visit prep you tick off in the room
Three questions to ask, three symptoms to mention, three documents to bring — with a progress bar on the home screen counting down to the appointment.
Trial criteria worksheet
Six disease classes, nine inclusion and exclusion criteria each, marked Meets / Blocks / unknown, with a running count of what is blocking enrollment.
One timeline, exportable
Diagnoses, medication starts and stops, severe symptom days, documents and visits merged into one chronological page you can download and hand to a new specialist on visit one.
